NEW JERSEY, A CORPORATION OF NEW REVOLUTION COUNTING AND STOP MECHANISM.

Application filed June 23, 1925.

This invention was designed for use in the manufacture of coated webs. such as carbon paper for billing, duplicating and adding machines. Such fabrics are sold in units of seventy-five lineal feet. but in rolls containing from one to twelve pieces, arranged as parallel plies, in accordance with the kind of machine in which they are to be used, but the length of each piece should be aliquot to such unit length. Therefore, it is highly desirable to have means to limit the cutting of such fabrics to the precise aliquot lengths required, to avoid waste of the materials; and the object and effect of my invention are to provide such means.

As hereinafter described; a convenient embodiment of my invention is accessory to a roller, hereinafter termed the measuring roller, over which such fabric is so progrossed as to revolve that roller in accordance with the length of the fabric passed thereover. That accessory device includes an index dial, connected with said roller, by suitable gearing; so that the passage of each such unit length of fabric effects one revolution of said dial. Said dial is arranged as the terminal of one side of an electric circuit and provided with a plurality of concentric circular series of electric contact pins; for instance in the form illustrated, there are twelve such series respectively including from twelve to one such pins; which are equally spaced in their respective series. Said Contact dial is arranged to cooperate with a terminal of the opposite side of said circuit which is conveniently mounted on a slide bar which is adjustable so that said terminal. may be presented in registry with any one of the twelve series of pins. Such arrangement renders said accessory device operative to close the electric circuit, by contact of said terminals, any number of times from one to twelve, during each revolution of said dial, in accordance with the position to which said slide bar is set. In said embodiment of my invention; said electric circuit includes a source of cur rent and an electromagnetic tripping device for a clutch which is part of the 1ne;-hanism for progressing said fabric over said measuring roller and between shears so that it may be out the proper length, when stopped, each time the circuit is closed as aforesaid.

Serial No. 39,160.

That form of my device also includes convenient means enabling the operator to readily reset the trippii'ig mehanism and clutch to their norn'ial operative positions and my invention includes the various novel features of construction and arrangement hereinafter more definitely specified.

In said drawings Fig. I is a digrammatic elevation of a convenient embodiment of my invention.

Fig. II is a fragi'ncntary vertical sectional view of said dial and shows the connected position of said electric terminals. corresponding with the position thereof shown in Fig. I.

Fig. III is a fragmentary vertical sectional view of said electromagnetic tripping device.

Fig. IV is fragmentary sectional elevation of said tripping mechanism in cooperz tive relation with the'clutch mechanism and means for resetting the same. 7

In said figures; the measuring roller 1 is mounted. to rotate in a suitable frame of which part is indicated at 2 in Fig. IV. Said roller 1 has the shaft 8 provided with the worm 4t engaged with the worm gear 5 which is rigidly connected with the shaft 6 which carries said contact dial 7.

Said dial 7 is arranged as the terminal of one side of an electric circuit with which it is connected by the conductor 8, and is provided with. twelve concentric circular series of electric contact pins 9; said series respectively including from twelve to one such pins; which are equally spaced in their respective seris. Each contact pin 9 on said contact dial 7 is arranged to cooperate with the single spring terminal 10 which is arranged as the terminal of the opposite side of said circuit with which it is connected by the conductor 12. Said terminal 10 is conveniently mounted on the slide bar 13 which carries the insulating base 14 to which the upper end of said terminal 10 is rigidly connected. Said slide 13 is vertically adjustable in the bearing 16 which is supported by the machine frame 2, in any convenient manner. It is to be understood that the arrangement is such that said terminal 10 may be presented in registry with any one of the twelve series of pins so that said device is eperative to close said twelve, during each revolution of said dial e ectric circuit by contact of said terminals 9 and 10, any number of times from one to T, in accordance with the position to which said slide bar 13 is set, in the radial guide bearing 16. is shown in Fig. I, said slide 13 is set in its uppermost position, with the upper e-Cg of the bearing 16 in registry with the graduation 12 on said slide, which thus presents said terminal in registry with the twelve terminals 9 in the outermost circular series on said dial 7 so that. as thus adjusted, said device is operative to close said electric circuit by rontact of said terminals 9 and i0 twelve times during a single revolution of said dial 7.

Said electric circuit, comprising said con ductors S and 12, includes the source of current 18 and the electromagnetic tripping device 19, as diagraminatically indicated in Fl I. is indicated in Fig. III; said tripping device 19 comprises the electromagnet 20 which is regidly mounted in the casing 21, below the armature 22, which is pivotally connected with said casing atits left hand end and conveniently by cone pointed screws in the opposite walls of said 21 which are parallel with the plane ot section of Fig. III. and said armature is normally upheld in the position shown in Fig. III by a suitable spring. In that position; said armature is ged by the movable latch wnich is pivoted at its upper end to said casing and has a suitable notch engaging the pin 26, projecting from the tripping lever 21' which is fulcrumed at 28 in said casing and normally uptur ed to the position shown in Fig. III by the spring 30.

In the normal position of the parts shown in Figs. III and IV; said tripping lever 2? extends beneath the hook link 31 which then engages, in its notch 32, the stop projection 3% on the frame 2. Said link 31 is carried by the clutch shifting yoke which is tulcrumed at 86 and operatively connected with the groove hub 88 of the cone clutch member 39. Said clutch member 39 is .connected with a suitable electric motor or other means for driving the fabric feed roller lO; which latter may be either directly or indirectly connected with the complementary conical clutch member t1; so that, when the parts are in the position shown in Figs. III and IV; said roller is rotated to progress the fabric 4E2 which is to be measured as aforesaid.

The construction and arrangement above described are such that whenever said electric circuit is closed to energize said electromagnet 20: said armature 22 is drawn down below the end of said latch 25 thus permitting the latter to be swung to the left by said pin 26 on the tripping lever 27, as

said lever 2': is drawn down under tension of said spring 30; thus said tripping lever 27 is tilted by its spring 30 to trip said hook link 31 out of engagement with said projection 32, shown in Fig. IV. 'Ihereupon, said clutch member 39 is xially shifted, to the right in Fig. IV, by the spring 3 con nectcd with the arm to on said yoke 35, to thus disconnect said feed roller do from its driving mechanism and stop the progression of the fabric ll through the machine after a predetermined length of such fabric has been passed over said measuring roller 1; such length being variably predetermined by the adjustment of said terminal 10. That is to say; each measured length of the "ahric slit may correspond with from one-twelfth ot a revolution of said dial 7, up to acomplete revolution thereof. However, the dimensions specified are merely convenient to satist'y the trade demands for the multip e carbon paper rolls aforesaid, it is obvious that the relations of the suring roller and dial may be different in ccordance ith the units oi measurement desired.

i v'hen said mechanism has been thus automatically electrically tripped and stopped: said armature is held down, in abnormal position, by said latch which has been swung over it by the pin 26 of the tripping lever 27 and, consequently, it is necessary to reset said tripping mechanism to the position shown in IV; to perform another measuring operation. I find it convenient to effect such resetting by means of the pedal lever l7, which is normally upheld in the position shown in Fig. IV, by the chain l8 pendent from the spring 929 attached at its upper end to the frame member 'l. Said chain 48 has the branch 51 connected at its upper end with the arm of salt yoke 37 and is of such length that the first erect. of depressing said pedal 4-7 is to reset said yoke to the position shown in Fig. IV with its hook lever 31 engaged with said frame projection 32, so as to detain the clutch device in position to rotate said roller 1. until the tripping operation aforesaid is repeated. However, said chain 418 has the second branch 54: which is connected by the spring 55, with said tripping lever 27, so that farther downward movement of said pedal d7 resets said tripping mechanism to its initial normal position shown in Fig. III.

r-llthough I have found it convenient to employ the contact dial mechanism aforesaid with the forms of tripping and clutch mechanism which I have illustrated: it is to be understood that it may be used in conjunction with either tripping mechanism or clutch mechanism of other forms.

Therefore, I do not desire to limit myself to the precise details of construction and arrangement herein set forth, as it is obvious that various modifications may be made an d therein without departing from the essential features of my invention, as defined in the appended claims.

I claim:

1. In revolution counting and stop mechanism; the combination with a measuring roller; of driving mechanism for said roller, including a clutch mechanism comprising a spring normally tending to release said clutch and a hook arranged to hold said clutch in operative position until tripped; an index dial; means constituting said dial the terminal of one side of an electric circuit; a source of current included in said circuit; an electromagnetic trippin device included in said circuit, in cooperative relation with said clutch hook; a train of gearing operatively connecting said roller with said dial; including a worm driven by said roller and a worm gear operatively connected with said dial; a plurality of concentric circular series of electric contact pins, carried by said dial; said serles including respectively different numbers of pins, symmetrically spaced in their respective series; a terminal of the opposite side of said circuit, comprising a spring; means supporting said spring terminal, including an insulating base mounted on a slide bar; and a guide bearing for said slide bar, in radial relation with the axis of said dial; whereby said slide bar is adjustable to present said sprin terminal in registry with any one of sai several series of contact pins, to close the electric circuit, by rotation of said dial, the number of times per revolution determined by the number of pins in such registered series, and thereby stop the rotation of said roller each time said circuit is closed.
